i also have this problem when i try to OC my KVR from DDR3 1333 to DDR3 1700 or above, CL9...

if CL8, I will have problem when reaching DDR3 15xx.

if CL7, I will have problem when reaching DDR3 14xx.

The lesser ram detection problem only occurs when I run my ram out of spec. But still can OC, luckily didnt buy high end expensive ram for the board. Seems the board not so good in Ram OC.

lol... gotto agree p6t quite picky for ram and lousy in ram OC.

But during the old days, p6t were one of the bang of buck board with SLI + CF, but not now especially all those DKs year end clearing sales. I might wait till next year for the new DK with USB 3.0 before swapping my p6t since not so worth if go for DK now juz for additional OC headroom without any new features like USB 3.0.

so for all p6t user better not invest too heavily on good ram... feel the frustration of TS after invest in good ram.
